AS8817 OMSK-SBRAS Campus network OSC - abbrivate in russian for

OMSK-SBRAS is held by the Sobolev Institute of Mathematics of the Siberian Branch of the Russian Academy of Sciences. The AS serves the Omsk Scientific Centre campus network — the handle's trailing text is a half-finished gloss noting that "OSC" is an abbreviation in Russian, which is why the raw string reads as a broken sentence.

What it's used for

An academic campus network for the Russian Academy of Sciences' Omsk research institutions. It announces a single /22 (217.79.52.0/22, ~1,024 addresses) plus one IPv6 prefix, with exactly one observed BGP neighbour. The only PTR returned in the sample is GateRouter.omsknet.pro — the campus edge router, named in plain English and sitting exactly where an academic network's single upstream link would be.

Notable

• The Sobolev Institute is one of the Russian Academy of Sciences' principal mathematics institutes, headquartered in Novosibirsk with the Omsk department operating semi-independently. The AS covers the Omsk side, not the much larger Novosibirsk Akademgorodok networks, which are numbered separately.
• The routing is minimal by design. A thousand addresses behind one upstream is a research campus with a single connection to the national academic network, not an operator. It has no downstream networks and sells nothing.
• The first seen record for this AS dates to 2004, and its current prefix is a later RIPE assignment than the block originally associated with it — the usual sign of a campus renumbering at some point rather than a reissue of the AS to a new holder.
